mission experts will talk about the robotic scientist’s touchdown in the most challenging terrain on Mars ever targeted.

Perseverance, which launched July 302020, will search for signs of ancient microbial life, collect carefully selected rock and regolith (broken rock and dust) samples for future return to Earth, characterize Mars’ geology and climate, and pave the way for human exploration beyond the Moon.

Tune in to watch a live broadcast from the Von Karman Auditorium at NASA’s Jet Propulsion Laboratory.

Almost one in five people lack the protein α-aktinin-3 in their muscle fiber. Researchers at Karolinska Institutet in Sweden now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibers, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibers. The results are published in the scientific journal The American Journal of Human Genetics.

Skeletal muscle comprises fast-twitch (white) fibers that fatigue quickly and slow-twitch (red) fibers that are more resistant to fatigue. The protein α-aktinin-3, which is found only in fast-twitch fibers, is absent in almost 20 percent of people – almost 1.5 billion individuals – due to a mutation in the gene that codes for it. In evolutionary terms, the presence of the mutated gene increased when humans migrated from Africa to the colder climates of central and northern Europe.

“This suggests that people lacking α-aktinin-3 are better at keeping warm and, energy-wise, at enduring a tougher climate, but there hasn’t been any direct experimental evidence for this before,” says Håkan Westerblad, professor of cellular muscle physiology at the Department of Physiology and Pharmacology, Karolinska Institutet. “We can now show that the loss of this protein gives a greater resilience to cold and we’ve also found a possible mechanism for this.”

We all know the benefits of saunas on our mental and physical health, indeed, I recently did a video on just that, but what about the home saunas that are available so you can get the benefits as often as you desire, without having to leave the comfort of your own home, especially relevant in the current climate and recurring lockdowns… Well I have been testing both steam and infrared varieties extensively over the last year and have put together a quick guide on the pros and cons on both types. So if you have been thinking about investing yourself, or indeed you want to know which type is best for you, why not check out this video for further information. Have an awesome day…

Having already looked at the benefits of saunas, just how do home portable saunas stack up. Are they worth the expens…

EMP Shield is the Worlds First entire home EMP protection device. The Shield also protects against, lightning, solar storms, power surges & smart meter fire.

In a recent interview, he said the next big disasters facing humanity are climate change and bioterrorism.

One day a “magic carpet” based on this light-induced flow technology could carry climate sensors high in the atmosphere—wind permitting.

Building a corn cob—cell by cell, gene by gene.

Corn hasn’t always been the sweet, juicy delight that we know today. And, without adapting to a rapidly changing climate, it is at risk of losing its place as a food staple. Putting together a plant is a genetic puzzle, with hundreds of genes working together as it grows. Cold Spring Harbor Laboratory (CSHL) Professor David Jackson worked with Associate Professor Jesse Gillis to study genes involved in corn development. Their teams analyzed thousands of individual cells that make up the developing corn ear. They created the first anatomical map that shows where and when important genes turn on and off during key steps in development. This map is an important tool for growing better crops.

This coating might prove useful for several sorts of applications.

Managing temperatures in particularly hot and sunny climates can be very difficult even today. You can use air conditioning to displace the heat from inside structures and vehicles, but it sucks up so much power and can generate pollution that ultimately makes temperature problems even worse.
